Title: Picture sampling device of computer output image
Inventor: KATO NAOKI
IPC: G06F3/153
Filed: 1992-03-06
Abstract: PURPOSE:To provide a picture sampling device of a computer output image capable of sampling a good quality image without receiving any influence of a clock jitter component by controlling the phase of a sampling pulse sampling an input computer image signal. CONSTITUTION:A computer output image 7a is input to an image signal input portion, is synchronized to the horizontal synchronizing signal 7b of a computer output image signal, and is converted digitally by an A/D conversion circuit 10 with a clock signal having an equal frequency to a pixel dot frequency. The generated image signal data 7g thereby, and the absolute value sum of the amplitude difference data of an image signal at a same position being apart one field or more of the image signal data 7h in an area including horizontal direction edge out of the image signal data 7g, are compared each other. The clock phase of a sampling pulse is controlled so that the absolute value sum takes the minimum value. Thereby the input computer output image is converted digitally.

Title: Three-wavelength selecting type liquid crystal optical switch
Inventor: IWAKI TADAO
IPC: G02B27/28
Filed: 1986-04-10
Abstract: PURPOSE:To select three kinds of wavelength by using many stages of optical filters and beam splitters to take out a P-polarized light in a three-wavelength area. CONSTITUTION:An incidence light in the wavelength area of wavelengths lambda1, lambda2, lambda3, lambda4, lambda5, and lambda6 (lambda1>lambda2>=lambda3>=lambda4>=lambda5>lambda6) is made incident on an optical filter 1 which intercepts >=90% of the light having a wavelength longer than lambda1 and permits >80% of the light having a wavelength shorter than lambda1 to pass through. The light transmitted through the filter 1 is converted to a P-polarized band light having a wavelength lambda1-lambda2 by a narrow band polarizing beam splitter 2 which is operated with the wavelength lambda1-lambda2 and reflects >=95% of the light having a wavelength shorter than lambda2, and this P-polarized band light passes a mirror 7 for wavelength lambda1-lambda2 and is made incident on an optical switch where a liquid crystal is sealed. A P-polarized band light having a wavelength lambda3-lambda4 and that having a wavelength lambda5-lambda6 are formed similarly by combination of optical filters, beam splitter, etc., and are made incident on a driving part 8, and thus, a three-wavelength selecting type liquid crystal switch of high reliability is obtained which has a high light transmittance even for a short wavelength light area and has a wide applicability and does not require narrow band filters and upon which the influence of change in the lapse of time is little.

IPC: G02F1/37
Filed: 1989-03-31
Abstract: PURPOSE:To collimate or converge the 2nd higher harmonic beam of light projected by a fiber type optical waveguide and to facilitate the manufacture by tapering the light projection end surface of a Cherenkov radiation type wavelength converting optical element. CONSTITUTION:The light projection end surface of a clad part 12 is so tapered as to convert a conic wave into a plane or spherical wave. For example, the optical waveguide consisting of, for example, a core 11 and the clad 12 is an aixally symmetrical fiber type optical waveguide. Then a fundamental wave 13 is entered into the core 11 from a light incidence end surface and Cherenkov emitted light which is propagated into the clad 12, i.e. the 2nd higher harmonic 14 is projected from the light projection end surface. Consequently, the 2nd higher harmonic beam 14 of the light projected from the fiber type optical waveguide can be collimated or converged without being in a ring shape and the manufacture can be facilitated and reduced in cost.

IPC: H01L29/73
Filed: 1983-05-12
Abstract: PURPOSE:To reduce the stepping on the isolated region generated when an aperture is formed as well as to prevent the short-circuit on the stepped part by a method wherein an inert base region is formed by diffusion on an oxide-isolated island region using an oxidation-resistant film as a mask. CONSTITUTION:After an oxide film 5 and a region 7 which will be turned to a collector have been formed on the main surface of an N type Si substrate 1, an Si3N4 film is deposited, and the Si3N4 films 10a and 10b only located on the region 7, its circumference and on the desired region other than the above is left. At this time, no large stepping is formed at a groove part 6b, because the etching rate of the film 5 is different from that of the other heterogenous substance. Subsequently, regions 11a and 11b which will be turned to an inert base are formed by diffusion using the films 10a and 10b as a mask. Then, the film 10a located on the region 7 is removed and, at the same time, oxide films 12a and 12b are selectively formed using the film 10b as a mask. Then, a region 13 which will be turned to an active base and a region 14 which will be turned to an emitter are formed using the films 12a and 12b as a mask. In this case, as there is no large stepping on the groove part 6, etching remnant on an electrode disappears.
